Sontia SPT is a technically advanced and novel approach to the creation of premium audio in headphones, without the need to compromise on the headphone design and components choice.

Sontia’s multi-patented, unique, SPT algorithms mathematically reverse the distortions in the headphone speakers and enclosure, in both time and frequency domains, so the faulty effect in the speakers are removed and the output sound is almost identical to the original audio signal.
